TOOL-HANDLE rascrnnmo.

Application filed September 25, 1926. Serial No. 137,698.

This invention relates generally to tools and has more particularreference to means to facilitate the attachment of the tools to thehandle and the primary object thereof resides in the provision of suchmeans that will enable a broken tool to be replaced by a new toolwithout necessitating the discarding of the handle or that will enable abroken handle to be replaced by a new handle without necessitating thediscarding of the tool which is now the case by reason of the form offastening now generally in use.

lVith the foregoing and other objects in View as the nature of theinvention will be better understood the same comprises the novel form,combination and arrangement of parts hereinafter more fully shown in theaccompanying drawing and claimed.

In the drawing wherein like reference characters indicate correspondingparts in both of the views Figure 1 is a view of a tool and handleinterconnected by fastening means st-ructed in accordance with thepresent invention, said fastening means being disclosed incross-section, and

Figure 2 is an elevation of the handle and tool in separated condition.

Now having particular reference to the drawing 5 designates a toolhandle of conventional construction, while 6 designates a tool which inthe present instance is shown as being a shovel. In carrying out myinvention the tool is formed with a shank 7 the inner end of which isreduced and externally screw threaded as at 8. Arranged over the toolend of the handle 5 is a relatively elongated sheet metal sleeve 9 thatis formed inwardly out of the tool attaching end with a wall 10 thatabuts the end of the handle 5 so as to permit the securing of the handleto the wall by reason of a wood screw 11. The said end of the sleeve 9outwardly of the wall 10 is internally threaded for receiving thethreaded reduced extension 8 of the tool shank 7.

con-' Afterthe sleeve 9 has been arranged upon the handle and securedthereto by reason of the wood screw 11 there is arranged transverselythrough the inner end of the sleeve and said handle a bolt 12 upon thethreaded end of which is arranged a nut 13.

It will thus be seen that should the tool. or handle become bro-ken inthe first event the toolfcould be readily removed by unscrewing! thesame from the sleeve 9 and a new tool substituted in lieu thereof. Onthe other hand should the handle become broken it would only benecessary to remove the bolt 12 and the screw 11 and a new handleassociated with the sleeve and then attached thereto by reason of saidscrew and said bolt.

Even though I have herein shown and de scribed the invention asconsisting of certain detail structural elements it is nevertheless tobe understood that some changes may be made therein without affectingthe spirit or scope of the appended claim.

Having thus described my invention what I claim as new and desire tosecure by Let ters Patent, is

In a tool handle fastening of the class described, wherein the tool isprovided with a reduced externally threaded extension on the outer endof its shank, an elongated sleeve constructed for slidable engagementover the tool end of the handle, a transverse wall formed in the sleeveadjacent its outer end for abutting engagement with the inner end of thetool handle, a screw extending centrally through the wall into theadjacent end of the tool handle, the outer end of the sleeve beinginternally threaded for receiving the externally threaded reducedcxteir' sion formed on the shank of the tool, the outer end of saidreduced extension abutting the inner side of said transverse wall, and aboltextending transversely through the inner end of the sleeve and theadjacent portion of the handle.

In testimony whereof I afiix my signature.

CONRAD HENNECK.
